The drift speed of electrons in copper wire of diameter and length `l` is `v` . If the potential difference across the wire is doubled, then the new drift speed becomes

What is the drift speed of electrons ?

The drift velocity of free electron in a metal wire of a given potential gradient along it is V_(d) . If this potential gradient is doubled the new drift velocity will be

The following table gives the length of three copper wires, their diameters and the applied potential difference across their ends. Arrange the wires in increasing order according to the following The drift speed of electrons through them?

An electric cell of e.m.f E is connected across a copper wire of diameter d and length l. The drift velocity of electrons in the wire is v_(d) . If the length of the wire is changed to 2l, the new drift velocity of electrons in the copper wire will be
